High-Purity Sodium Cyanide for Organic Synthesis
High-purity sodium cyanide (NaCN) in ACS reagent grade, used as a reagent in organic synthesis to produce pharmaceutical intermediates. It is a separate chemically defined compound of sodium, meeting the criteria of Chapter 28 Note 1, and is not an organic nitrile, which falls under Chapter 29.
2837.11.00Industrial Sodium Cyanide Pellets
Pelletized sodium cyanide for automated dosing in mining leach circuits, with a polymer coating for dust control. It remains a chemically defined sodium cyanide compound, as the polymer coating is an addition for safety and does not alter its classification under Chapter 28 Note 1(e).
2837.11.00Pharmaceutical Grade Sodium Cyanide Crystals
Ultra-pure sodium cyanide crystals (99.9%) for laboratory and pharmaceutical synthesis of nitriles. This is a separate chemically defined compound of sodium, meeting Chapter 28 Note 1 criteria, and is not an organic derivative, which would fall under Chapter 29.
2837.11.00Sodium Cyanide Briquettes
Sodium cyanide (NaCN) compressed into briquette form for safe handling and transport in industrial applications. The briquette form does not change the chemical identity; it remains a separate chemically defined compound of sodium, meeting Chapter 28 Note 1 criteria.
2837.11.00Sodium Cyanide Flakes
Flake-form sodium cyanide, a white crystalline solid used in hydrometallurgical extraction of gold and silver. It is a separate chemically defined compound of sodium, meeting Chapter 28 Note 1 criteria, and is distinct from complex cyanides in heading 28.42.
2837.11.00Sodium Cyanide for Electroplating Baths
